[Also in Divisions C1 and H1] A zinc oxide film is produced on a substrate by first depositing a zinc selenide or zinc sulphide film on the substrate, and then oxidising the film at least partially to zinc oxide. The selenide or sulphide film may be deposited on a variety of substrates e.g. glass, ceramics, mica, plastics, quartz, metals, by vacuum evaporation, using resistance heating or electron beam heating, by spattering under reduced pressure, by vapour deposition in the presence of a stream of zinc selenide or by thermal decomposition. The selenide or sulphide film should be oxidised at a temperature above that required to sublime the SeO 2  or SO 2 . Suitable oxidising agents are air, oxygen, oxygen/ inert gas/water mixture. The oxygen may be ionised. When using ionised gas as an oxidising agent, oxidation may be carried out at ambient temperature, and the film afterwards heated to vaporise the SeO 2  or SO 2 . Additives may be incorporated in the selenide or sulphide, before or after deposition so as to modify the properties of the resulting oxide film. Suitable additives include Al, In, Tl, Ga, Aue, Ag, Cu, alkali metals, Te, and rare earth metals. In a modification of the process, the oxide film may be removed from the substrate, or the ZnS or ZnSe film may be removed from the substrate and then oxidised.

Abstract: 1296689 Electrophotographic processes BELL & HOWELL CO 20 Nov 1969 [21 Nov 1968] 56954/69 Heading G2H [Also in Division H1] An electrophotographic imaging process utilizes a recording element comprising photo-conductive and thermal electret materials either mixed together or in separate layers; a thermal electret material being a dielectric which becomes polarized when allowed to solidify in a D.C. field e.g. Carnauba wax (RTM), beeswax, polymethylmethacrylate. In use, the photo-conductive material is imagewise exposed and the exposed portions are heated (e.g. by passing an electric current through them) to melt the adjacent portions of the thermal electret material. The thermal electret material can then be subjected to the D.C. field as it solidifies, whereby to form an electrostatic latent image which can be repeatedly developed and transferred. Alternatively the thermal electret material can be uniformly polarized before imaging, the melted portions formed during imaging becoming depolarized. The latent image may be removed by heating.

Abstract: 1297657 Casting processes UNITED AIRCRAFT CORP 1 Dec 1970 [10 Dec 1969] 57066/70 Heading B3F [Also in Division C7] A composite material comprising a matrix phase and a dispersed aligned fibrous or lamellar carbide phase is cast from a quartenary material system of eutectic composition which material system is thermodynamically multivariant. The following alloy compositions may be used (in wt. per cent). The required structure is formed by unidirectional solidification of the alloys along a macroscopically planar front at 2-20 cm./hr. 10 cm./hr. is specified for alloy (I) above and 8 cm./hr. for alloy (IV) above.

Abstract: 1297982 Measuring displacement electrically COMMISSARIAT A L'ENERGIE ATOMIQUE 8 Dec 1970 [8 Dec 1969] 58221/70 Addition to 1173438 Heading G1N Micro-wave energy from generator 32 frequency modulated by a sawtooth wave is supplied to a reference cavity 20 and test cavity 6 the volume of which is determined indirectly, as shown, in Fig. 1 by the displacement of member 2 or directly Fig. 3. The power transmitted by the cavities 6, 22 is detected at 22, 104 and applied to bi-stable circuits 401, 402 which change state when the Klystron generator 32 sweeps through the respective resonant frequencies of the cavities and are restored to their initial states at the end of the sawtooth sweep. If the resonant frequencies of the cavities are different due to a difference in volume differential amplifier 404 applies a signal to energize motor 108 to move plunger 28 in a direction to bring the resonant frequencies of the cavities 6, 20 into agreement and nullify the output of amplifier 404. The displacement of plunger 28 as measured by micro-meter 30 and potentiometer 110 gives a measurement of the displacement of element 2. The frequency range of generator 32 may be selected by switch 405. Thickness measurement, Fig.3. The thickness of metal strip or sheet 306 may be measured by using two test cavities 6, 6<SP>1</SP> arranged symmetrically on opposite sides of the sheet 306 and taking the place of plunger 4 of Fig. 1. The outputs from bi-stable circuits 401, 401<SP>1</SP> are each compared with the output from reference bi-stable circuit 402 in comparators 408, 408<SP>1</SP> so that if the sheet 306 does not take up a strictly centered position between the cavities 6, 6<SP>1</SP> the cavities have different resonant frequencies and circuit 410 delivers at its output 411 square waves which activate follow-up control circuit 404. Piston 28 is thereby displaced until its resonant frequency assumes a value which is the mean value of the resonant frequencies of the test cavities 6, 6<SP>1</SP>. The positional variations of plunger 28 will represent one half the difference in thickness between two successive plates 306 disposed between the cavities.
